WILLIAM? L. Larsen, or nrninson, 'nnnnnska METER non MILKrNG APPARATUS.

Application :lled January 24, A1921.

To @ZZ whom t may cof/wem:

Be it known that I, WILLIAM L, Linsen, a citizen ot' the United States,residing at Atkinson, in the county of Holt and State of Nebraska, haveinvented a new and useful Meter for Milking Apparatus, of which theiollowing is a specification'.

The object ot my invention is to provide a. novel meter for use inconnection with milking apparatus of the double unit milker type, whichwill make it possible to weigh themilk of each cow and enable thedairy-- man to keep an accurate record for obvious reasons. I attain theobject of my invention by the mechanism illustrated in the ac-"companying drawings, in which* Figure 1 is a side elevation of themeter applied to the milking apparatus;

Fig. 2 is an enlarged side elevation of the meter;

Fig. 3 is a cross section through the meter;

Fig. 4 is a longitudinal section partly in elevation through the metershowing the double cup in one of its extreme positions;

Fig. 5 is a longitudinal section through the meter, double cup anddischarged nozzle, with a double cup shown in its other extremeposition;

Fig. 6 is a section on line 6 6 of Fig. 2; and

Fig. 7 is a detailed perspective view of member 19.

Like numerals designate like parts of each of the views.

Referring to the accompanying drawings, a conventional milking-apparatusis shown consisting of a milk pail 7 having a cover S on which ismounted the conventional pul sator 6 of a vacuum milking apparatus. Theteat cups 4 are connected by the conventional milk tube 3 and valve 2with the cas-I ing 1 of the milk meter. Mounted in the upper portion ofthe meter casing 1 are trunnions 9 adjustably mounted in bearings l()and pivotally supporting the double cup partition 12 which carries thedouble cups 11. Mounted on partition 12 are screw threaded rods 14 whichcarry adjustable weights 15 adjustably mounted on rods 14. Partition 12is provided with an extension or lip 13 adapted to guide the milk intowhichever of the cups 11 is in position to receive same. Valve tubewhich is attached to the milk tube 3 terminates in a short tube 18,mounted in bearing 17 of the casing 1, and which tube iScarries thenozzle 19 which is provided Serial No. :4l-39,404.

with a discharge opening 20 in the form of an elongated slot or mouth,above which is positioned a suitable slot 21 to admit air to the nozzleso that the milk will fiow freely down through the mouth 2() into one ofther double cups 11, and subsequently through the discharge nozzle 26 otcasing 1 into the milk pail 7. I provide opposite stops 16 on the insideoit the casing disposed to limit the swinging movement of the cups 11and to retain same in the desired position while being lilled, as shownin Figs. 4 and. Casing 1 is provided with a suitable cover 25. l providea suitable trip finger 22 rigidly at-V tached to or connected with thepartition 12 ot the double cups and moving in unison therewith. Saidtrip finger is positioned to operatively engage the operated element 23of a comptometer 24. so that each swing ot the iinger 22 will registeron the comptometer 24.

In operation the milk flowing in through tube 3 and nozzle 19 whence itis discharged through mouth 20 into one of the double cups 11, the milkbeing guided by partition 12 and extension 13 into whichever cup is inuppermost position. The cups are of a suitable size and the weights 15suitably ad# justed so that the cups will hold a predeter` minedquantity of milk (preferably one tenth of one pound), and when thatweight has been received the weight of the milk in the uppermost cupwill over balance the weight 14 and cause the twin cups 11 to swing to areverse position, thereby dumping the milk from the cup into the casing1 and through its discharge nozzle 26 into the milk pail 7. The milkiiowing into the meter then liows into the other oit the two twin cups,which is now in uppermost position and the operation is continued, thetrip finger 22 operating` the comptometer actuated member 23 to registereach discharge of one of the twin cups 11, thus registering the weightAot the milk passing through the meter. @ne of the trunnions 9 isadjust-able or removable to permit ci removal ot the twin cups forcleaning the device. The other trunnion 9 operatively connects the twincup partition 12 with oscillating trip finger 22, as will be understoodby reference to Figs. 3 and 6. Trunnion 9 includes a thumb nut on itsouter end as shown.

The meter makes possible the weighing of the milk of each cow with amilking apparatus of the double unit milker type.; and it also showswhen the cow refuses to give milk, and it simplifies tlie making ofrecords of the Weight of milk obtained. The lid or" the meter casing caneasily be removed as it is held in place merely by the vacuum producedby the milking' apparatus, and is released when the vacuum is shut oit.

It is Within the contemplation of my invention to make minormodifications in the mechanism for operating the meter Without departingessentially jr'rom the apparatus described and shown.

Vilhat I claim is:

1. n combination with the milkingF apparatus of the class described, ameter comprising a casing' having` a cover normally held to its seat bythe vacuum produced by the milking apparatus, twin cups pivotallysupported Within the casing, adjustable means for overloalancing theWeight ot the cups and the contents of the uppermost cup up to,

a predetermined Weight, means tor limiting the upward oscillatingmovement of the cups When the Weight of the milk in the uppermost cupcauses it to discharge the milk and reverse its position, and means fordischarging the milk into Whichever ot the twin cups is uppermost, saidmeans being connected said trip iinger, and means for the free dischargeof milk into the uppermost twin cup from the milking apparatus.
